Reach router refresh page

Question

Setup: I have a form that send data to an action creator, which in turn submits to an API and gets the result. What I want is when the form submits successfully, to refresh the form with blank inputs.

This is how the component looks like

import React, { Component } from "react";
import { bindActionCreators } from "redux";
import { connect } from "react-redux";
import { addNewProduct } from "../../redux/actions";

class Admin extends Component {

    state = {
        ProductName: ""
    };

    onChange = e => {
        e.preventDefault()
        this.setState({
            [e.target.name]: e.target.value
        })
    }

    handleProductSubmit = (event) => {
        event.preventDefault();
        this.props.addNewProduct(
            this.state.ProductName,
        );
    }

    render() {
        return (
            <div>
                {/* Form ends */}
                <form onSubmit={this.handleProductSubmit} autoComplete="off">

                        <input
                            type="text"
                            value={this.state.ProductName}
                            name="ProductName"
                            onChange={this.onChange}
                        />

                    <button type="submit" className="btn btn-dark">
                        Upload Product
                    </button>
                </form>
                {/* Form Ends */}

            </div>
        );
    }
}

const mapDispatchToProps = (dispatch) => {
    return bindActionCreators({ addNewProduct, createNewLogin }, dispatch);
};

export default connect(null, mapDispatchToProps)(Admin);

This is the result of the console.log(this.props)

location: Object { pathname: "/Home/admin", href: "http://localhost:3000/Home/admin", origin: "http://localhost:3000", … }
navigate: navigate(to, options)
​​
length: 2
​​
name: "navigate"
​​
prototype: Object { … }
​​
<prototype>: ()

This is how the actionCreator looks like

export const addNewProduct = (ProductName, ProductCategory, ProductImg) => (dispatch) => {

    const productData = new FormData();
    productData.append("ProductName", ProductName)
    axios.post("http://localhost:4500/products/", productData,
        {
            headers: {
                "Content-Type": "multipart/form-data",
                "Authorization": localStorage.getItem("Authorization")
            }
        })
        .then(res => {
            console.log(res.data)
            setTimeout(() => {
                console.log("doing the timeout")
                navigate("/Home/admin")}, 1500);

        })
        .catch(err =>
            console.log(`The error we're getting from the backend--->${err}`))
};

Current behavior

When I submit the form and the API return 201, the page does not refresh and the inputs do not go blank

Expected behavior:

When I get a 201 from the API, the page should refresh and the inputs should be blank.

Please help me how to achieve this.

Using navigate to move the same url or page won't remount the page and reset your field values.

Its better is you actually return a promise from your action creator and reset the state yourself

export const addNewProduct = (ProductName, ProductCategory, ProductImg) => (dispatch) => {

    const productData = new FormData();
    productData.append("ProductName", ProductName)
    return axios.post("http://localhost:4500/products/", productData,
        {
            headers: {
                "Content-Type": "multipart/form-data",
                "Authorization": localStorage.getItem("Authorization")
            }
        })
        .then(res => {
            console.log(res.data)   
        })
        .catch(err =>
            console.log(`The error we're getting from the backend--->${err}`))
};

In the component

handleProductSubmit = (event) => {
    event.preventDefault();
    this.props.addNewProduct(
        this.state.ProductName,
    ).then(() => {
        this.setState({ProductName: ""})
    });
}
